The point where the roof meets the outer walls of the house is called the ROOFLINE. However most people refer to it by the name of the main board that carries the gutter – the fascia or fascias.
Unfortunately, not many people are familiar with these terms, so we thought you might appreciate a few words of explanation.
The Fascia Board is the long, straight board that runs along the lower edge of the roof. The fascia is fixed directly to the roof trusses and usually does all the work of supporting the bottom row of tiles and carrying all the guttering.
This is no mean feat, especially when it is raining hard. In a downpour the roof of a 3-bed semi could be washing several gallons of water per second into its gutters.
This is the board that is used on the gable end of a house. The condition of the bargeboard can often make or break the look of a house, and over the years it has evolved into some very attractive shapes.
The Soffit Board is tucked away under the fascia board. It is usually the board that you see most of from street level. The soffit can be ventilated to allow the flow of air into the roof area. Alternatively ventilation can be provided over the top of the fascia board. Many people prefer the latter solution these days. Without adequate ventilation, condensation will form in the roof void increasing the risk of timber decay.
The Box End is a work of art, accommodating as it does the many different angles, planes and heights of the fascia, soffit and bargeboard at each corner of the house where there is a gable end.
